Further, although the existing sewage treatment equipment is numerous, because the equipment mainly faces impurities and dirt, if good plans and designs cannot be made for the equipment, the sewage treatment is not timely and the sewage treatment effect is not good; the equipment is easy to damage, and the whole drainage system is influenced due to the breakdown of the whole equipment caused by the damage of a part of the equipment; the whole equipment is not tightly sealed, and peculiar smell can be emitted by the equipment.

Furthermore, because the device is often placed at opposite corners, if the installation is convenient, and the regularity of the appearance is further improved, the whole indoor environment can be beautiful. And the more humanized design can further realize full automatization, intellectuality, man-machine with whole equipment, conveniently controls and uses.

Therefore, if the equipment which can be relatively independent and perfect, even automatically realize sewage treatment is provided and is applied to large-scale catering and office living areas, such as restaurants, dining halls, slaughterhouses and vegetable markets, the equipment can directly treat a plurality of solid-liquid mixed production and living sewage, particularly food and beverage garbage and the like, and primarily separate, collect and discharge the production and living sewage, so that the environmental sanitation can be maintained, the labor cost can be reduced, the pressure of a municipal sanitation sewage discharge pipe network can be relieved, the equipment has a plurality of advantages, has great market potential and meets the development needs of the future society.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are only intended as distances, other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

As shown in fig. 1 to 10, a sewage treatment apparatus according to a preferred embodiment of the present invention will be disclosed and described in detail, wherein the sewage treatment apparatus comprises a set of panels to form a solid-liquid separation chamber 2 and a water-oil separation chamber 3, wherein the panels comprise an inclined panel 26, the inclined panel 26 has a filtering hole 261, wherein the inclined panel 26 separates the solid-liquid separation chamber 2 and the water-oil separation chamber 3, and the filtering hole 261 communicates the solid-liquid separation chamber 2 and the water-oil separation chamber 3.

Specifically, a water inlet pipe 21 extends from the outside of the solid-liquid separation chamber 2 to the inside of the solid-liquid separation chamber 2, as shown in fig. 3A, wherein the solid-liquid separation chamber 2 is provided with a pusher housing 212, wherein the pusher housing 212 is at a certain angle with the panel forming the solid-liquid separation chamber 2. The sewage treatment apparatus provides a pusher 22 installed in the pusher housing 212, wherein the water inlet pipe 21 integrally extends from the outside of the solid-liquid separation chamber 2 to an upper position of the pusher housing 212 inside the solid-liquid separation chamber 2. Preferably, in order to allow the sewage to be treated via the inlet pipe 21 to be better treated by the impeller 22, an end of the inlet pipe 21 near the impeller 22 is designed as an arc-shaped notch, that is, the arc-shaped notch is adapted to the external feature of the impeller housing 212.

It is worth mentioning that, as shown in fig. 3B, the water inlet pipe 21 may also integrally extend from the outside of the solid-liquid separation chamber 2 to the upper position of the pusher housing 212 inside the solid-liquid separation chamber 2, one end of the water inlet pipe 21 close to the pusher housing 212 is integrally fixed with the pusher housing 212, and the cavity formed by the water inlet pipe 21 is communicated with the cavity formed by the pusher housing 212, so that the sewage to be treated passing through the water inlet pipe 21 can smoothly enter the pusher housing 212.

As disclosed above, the relationship between the water inlet pipe 21 and the impeller housing 212 is advantageous in that when sewage to be treated enters the impeller housing 212 through the water inlet pipe 21 for primary treatment, the sewage to be treated can be effectively prevented from contacting a top cover 202 detachably fixed to the upper portion of the solid-liquid separation chamber 2.

Further, since the pusher housing 212 is disposed at a certain angle to the panel forming the solid-liquid separation chamber 2, when the pusher 22 is mounted inside the pusher housing 212, it means that the pusher 22 is disposed at a certain angle to the panel forming the solid-liquid separation chamber 2.

It should be noted that, in order to provide the sewage treatment apparatus with a good sewage treatment effect, the pusher housing 212 is disposed at a lateral upper portion of the panel forming the solid-liquid separation chamber 2, so that when sewage to be treated enters the pusher housing 212 from the upper portion via the water inlet pipe 21, the sewage to be treated can flow through the pusher housing 212 by itself due to the gravity of the sewage to be treated.

In addition, a layer of grating 23 with filtering holes is arranged at an outer position of the pusher housing 212, as shown in fig. 4, the cross section of the filtering holes of the grating 23 is trapezoidal, wherein the diameter of the opening of the filtering holes at one side of the grating 23 close to the pusher 22 is smaller than the diameter of the opening of the filtering holes at one side of the grating 23 far away from the pusher 22. The design can effectively prevent the large solid substances contained in the sewage to be treated from flowing out along with the water flow through the filtering holes of the grating 23, thereby being beneficial to improving the solid-liquid separation efficiency of the sewage to be treated in the treatment stage.

Further, a first drain port 28 is formed at one side of the solid-liquid separation chamber 2, wherein the impeller housing 212 is connected to the first drain port 28, so that the cavity formed by the impeller housing 212 is communicated with the cavity formed by the first drain port 28. It should be noted that, as shown in fig. 5, the pusher 22 further includes a rotating shaft 222, a spiral sector 221 surrounding an outer surface of the rotating shaft 222, wherein an outer edge of the spiral sector 221 is provided with a tooth-shaped structure 223, wherein when the pusher 22 is mounted on the pusher housing 212, an end of the rotating shaft 222 is located outside the pusher housing 212. In other words, when the pusher 22 is mounted to the pusher housing 212, a portion of the pusher 22 is located inside the solid-liquid separation chamber 2 and another portion is located outside the solid-liquid separation chamber. Wherein the rotating shaft 222 located outside the solid-liquid separation chamber 2 is connected to an engine, and the engine can provide a driving force for the rotating shaft 222, so that the pusher 22 starts to operate.

Preferably, the tooth-like structure 223 is made of an elastic material, such as rubber, silicone, etc., according to the above preferred embodiment provided by the spirit of the present invention, wherein the tooth-like structure 223 is made of silicone. When the pusher 22 is driven to rotate by the driving force provided by the engine, the rotation shaft 222 enables the spiral sector 221 to rotate therewith, so as to drive the tooth-shaped structure 223 to rotate, and during the rotation, the tooth-shaped structure 223 can continuously contact the grating 23 to clean solid matters adhered on the grating 23, so that the filter holes of the grating 23 are effectively prevented from being blocked, and the stability of the sewage treatment equipment in use is guaranteed.

It is foreseen that the tooth-like structure 223 comes into contact with the grid 23, so that the tooth-like structure 223 and the grid 23 are better fitted to clear and prevent the blockage of the filtering holes of the grid 23 when separating the solid and liquid states of the sewage to be treated.

It is also foreseen that when sewage to be treated enters the impeller housing 212 through the inlet pipe 21, the sewage to be treated will flow through the groove positions formed by the grating 23 first due to its physical properties, and at this stage, the larger solid substances in the sewage to be treated will remain at the groove positions formed by the grating 23, and other substances (including oil, water and other small solid substances) in the sewage to be treated will flow to the bottom of the solid-liquid separation chamber 2 through the filtering holes of the grating 23. It is worth mentioning that at this stage, as the impeller 22 runs high, the larger solid matter remaining at the groove position of the grating 23 is conveyed to high along the spiral sector 221 structure by the impeller 22 and finally discharged through the first discharge port 28 communicated with the impeller housing 212. It is also worth mentioning that in the process of conveying the large solid substances upwards, the centrifugal force generated by the high-speed operation of the pusher 22 throws off the excessive water in the large solid substances, that is, the large solid substances discharged through the first sewage discharge port 28 are the solid substances drained by the pusher 22, thereby improving the efficiency of separating the solid and liquid forms of the sewage to be treated.

Further, the sewage treatment device provides a collecting barrel 801 and a collecting pipe 8011, and the collecting pipe 8011 connects the collecting barrel 801 and the first sewage outlet 28 respectively, so that the separated solid substances passing through the first sewage outlet 28 are collected into the collecting barrel 801 through the collecting pipe 8011, thereby effectively preventing the separated solid substances from polluting the environment around the sewage treatment device, and improving the usability of the sewage treatment device.

The sewage to be treated after the solid-liquid separation is firstly stored at the bottom position of the solid-liquid separation chamber 2, it is worth mentioning that the solid-liquid separation chamber 2 is further provided with a second sewage discharge outlet 25, at this stage, the sewage to be treated after the solid-liquid separation is subjected to a first precipitation treatment, that is, the smaller solid substances in the sewage to be treated after the solid-liquid separation containing the smaller solid substances are precipitated at the bottom of the solid-liquid separation chamber 2, and the rest components flow to the oil-water separation chamber 3 through the filtering holes of the inclined partition plate 26, and the precipitated smaller solid substances remained on the inclined partition plate 26 are discharged to the outside of the sewage treatment equipment through the second sewage discharge outlet 25.

Further, the sewage treatment device further provides a collecting barrel 802 and a collecting pipe 8021, the collecting pipe 8021 is respectively connected to the collecting barrel 802 and the second sewage discharge outlet 25, so that the separated solid substances passing through the second sewage discharge outlet 28 are collected into the collecting barrel 801 through the collecting pipe 8021, and therefore, the separated solid substances can be effectively prevented from polluting the environment around the sewage treatment device, and the usability of the sewage treatment device is improved.

As shown in fig. 7B, the sewage treatment equipment further provides a liquid guide tube 24, wherein one end of the liquid guide tube 24 located in the solid-liquid separation chamber 2 integrally extends upward to the lower part of the grid 23, and a cavity formed by the liquid guide tube 24 communicates the solid-liquid separation chamber 2 and the oil-water separation chamber 3, so that the sewage treated by the pusher 22 enters the oil-water separation chamber 3 through the cavity formed by the liquid guide tube 24 for further treatment. According to the structure and data of experimental tests, one end of the liquid guide tube 24 in the oil-water separation chamber 3 does not need to extend to the bottom of the oil-water separation chamber 3, because if the end of the liquid guide tube 24 extends to the bottom of the oil-water separation chamber 3, the sewage to be treated entering the oil-water separation chamber 3 through the cavity of the liquid guide tube 24 firstly reaches the bottom of the oil-water separation chamber 3, and the time required for separating grease in the sewage to be treated above a water layer is longer according to the physical principle that the densities of oil and water are different. Therefore, in order to ensure the working efficiency of the sewage treatment apparatus, the liquid guide pipe 24 only needs to be sufficient for guiding the sewage to be treated from the solid-liquid separation chamber 2 to the oil-water separation chamber 3.

As shown in fig. 2, according to the above preferred embodiment provided by the spirit of the present invention, wherein the oil-water separation chamber 3 is designed to have a large middle space and tapered upper and lower portions, wherein the upper portion of the oil-water separation chamber 3 has an oil storage chamber 303, wherein the oil-water separation chamber 3 provides a buffer plate 33, and both side portions of the buffer plate 33 are integrally fixed at an angle to the panels forming both side portions of the oil-water separation chamber 3, so that the buffer plate 33 divides the oil-water separation chamber 3 into a first chamber 301 and a second chamber 302, wherein the buffer plate 33 has a gap respectively formed at the panels forming the upper and lower portions of the oil-water separation chamber 3 to allow the first chamber 301 to communicate with both upper and lower portions of the second chamber 302. It is anticipated that, when sewage to be treated enters the oil-water separation chamber 3 from the solid-liquid separation chamber 2, the sewage to be treated first enters the first chamber 301 via the buffer plate 33.

It is worth mentioning that the first chamber 301 and the second chamber 302 share a conical structural space at the lower part of the oil-water separation chamber 3.

It is worth mentioning that the oil-water separation chamber 3 is further provided with a longitudinal partition plate 34, both side portions of the longitudinal partition plate 34 are integrally fixed to the panels forming both side portions of the oil-water separation chamber 3, wherein one end portion of the buffer plate 33 is fixed to one side portion of the longitudinal partition plate 34, in order to ensure a better working effect of the sewage treatment apparatus, the longitudinal partition plate 34 is integrally extended upward to a lowest position of the liquid guide pipe 24, and the longitudinal partition plate 34 has certain gaps respectively in the panels forming upper and lower portions of the oil-water separation chamber 3, so that the upper and lower portions of the first chamber 301 and the second chamber 302 can be communicated.

When the sewage to be treated flows through the part of the structure of the sewage treatment device, the sewage to be treated firstly impacts the buffer plate 33 from top to bottom, and the buffer plate 33 reduces the impact force of the sewage to be treated so as to keep the stability of the sewage inside the first chamber 301 when the sewage treatment device treats the sewage as much as possible. In the next stage, the sewage in the first chamber 301 can enter the second chamber 302 through the gaps between the upper and lower parts of the longitudinal partition 34, and the impact force of the buffer plate 33 on the sewage to be treated is reduced, so that the sewage to be treated in the second chamber 302 is not stirred.

It is anticipated that at this stage, the wastewater to be treated will be simultaneously subjected to separation of solids, water and grease.

Specifically, a small amount of solid matter contained in the sewage to be treated at this stage will gradually settle into the conical structure of the oil-water separation chamber 3 due to its own weight, while the remaining matter is mainly water and grease, and at the same time, grease can float on the upper part of the water layer due to the physical property that the density of water is greater than that of grease, that is, if the sewage to be treated inside the first chamber 301 can enter the second chamber 302 at a steady speed, the second chamber 302 can achieve a good oil-water separation effect.

It is worth mentioning that the oil-water separation chamber 3 is provided with a third sewage outlet 39, the collecting pipe 8021 is communicated with the third sewage outlet 39 and the collecting barrel 802 to collect the solid substances precipitated in the conical structure of the oil-water separation chamber 3 into the collecting barrel 802, so that the separated solid substances can be effectively prevented from polluting the surrounding environment of the sewage treatment equipment, and the usability of the sewage treatment equipment is improved.
